PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is migrating its SAP ERP system to AWS. They need to ensure high availability for the SAP Central Services (ASCS) instance. Which AWS architecture should they implement?
⚠ Common exam trap
Many candidates confuse the high availability requirements of SAP ASCS (which needs a cluster with VIP and fencing) with generic AWS HA mechanisms like Auto Scaling or RDS Multi-AZ, which are not designed for stateful SAP application services.

Correct answer & explanation
✓
Configure a two-node cluster with a virtual IP (VIP) using AWS Route 53 health checks and failover
SAP ASCS requires a highly available cluster with a virtual IP (VIP) that can fail over between two EC2 instances. AWS Route 53 health checks can monitor the VIP and update DNS records to redirect traffic to the standby node upon failure, providing the necessary high availability for the ASCS instance without relying on a single point of failure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure a two-node cluster with a virtual IP (VIP) using AWS Route 53 health checks and failover
Why this is correct
Cluster with VIP provides HA for ASCS.
- ✗
Run ASCS on Amazon RDS for SAP with Multi-AZ
Why it's wrong here
RDS is for databases, not for ASCS.
- ✗
Deploy ASCS on a single large EC2 instance
Why it's wrong here
Single instance is a single point of failure.
- ✗
Use an Auto Scaling group with a minimum of 2 instances
Why it's wrong here
Auto Scaling does not manage the virtual IP or state of ASCS.
